The European Steam release of World of Goo has been pushed back to February or March 2009.
No reason was given for the delay, and we're told copies bought on Monday at US release will continue to work just fine.
World of Goo is a brilliant PC physics puzzle game where living blobs of goo are used to build structures that wobble their way towards a goal - usually a pipe that hovers the remaining globules up.
You can try the magical formula for yourself in a freshly released demo on FileFront. It's only 33MB.
World of Goo was also released on WiiWare in the US earlier this week. We've got our fingers crossed for its arrival here on Friday.
